I figured I could send it back if I didn't like the functionality of two screens being one large resolution

Summary: So, I don't usually leave feedback about products unless I am really impressed with them. This is the case with the Matrox DualHead2GO Digital ME. I have two identical ASUS VS247 24 inch external monitors that I have had hooked up with my early 2011 MBP. One with a HDMI to mini display port adapter connected directly to the Thunderbolt (TB) port (the adapter is from Monoprice), and the other with a USB 2.0 to HDMI adapter (also from Monoprice, but basically a Displaylink...
Summary: This device worked well with my MacBook Pro running Mavericks. You do need to read the guides online to find how to make programs stick to one monitor or the other and so on, but I had it running just as I wanted inside half an hour, maybe less. I did find that running the dual monitors through this device took a lot of the Mac's power, which caused some programs to slow down slightly and be a bit less responsive (I'm very picky and want gamer levels of responsiveness...
Summary: I have a MacBook Air, Late 2010. This Matrox box works GREAT. It was nearly plug-and-play, with a little configuring, but nothing too hard for me, and I'm not a techy-computer programmer type. Anyways the images are great - I have two side-by-side acer 27" screens from CostCo. The only quirk is that notifications pop up in the center of the two screens, so you have to drag the dialog box to be able to read the notification, but that's a serious "first-world" problem...
Better to go with daisy chained thunderbold monitor or new docking stations coming out

Summary: Really limiting for Macs your better off going with a dual monitor through the new "docking" stations coming out as of late 2013 through mid 2014 OR if you have a Thunderbold display which already does this. Either way you will spend a few extra on that configuration but the Mac OS works better, the screen on a DualHead2Go looks like one big monitor. Items open in the middle of the monitor which is really half of the one monitor and half on another.
Summary: I used this for about 1 year, then it failed. I contacted Matrox as this is supposed to have a 2 year warranty but the manufacture date of my unit is 25 months so they said I was out of luck. Awful support for such a pricey unit.
Summary: Works great and has many screen options. although it is not the same as daisy chaining monitors. this will combine the two external monitors into one giant monitor. for instance my screen #2 is 3840x1080.
Summary: Works as advertized. Easy install and good functionality. No delay or screen tearing. The only drawback is as others mentioned that the screen is one big screen and not 2 seperate screens. There is a shortcut that can be setup in the Matrox tools though to make the current application maximized to one of the 2 screens.
Amazing product that's sure to give you everything you want.

Summary: This product was exactly what I was looking for. I have a late 2011/early 2012 15" Macbook Pro. If you know, this thing is a beast. One of the best laptops I've ever had and it's still top of the line IMO. But with as much as I travel with it, it's biggest issue was that I didn't have the ability to also have a desktop. I'm a music producer and dj so I really needed help building a workspace for me to really focus on the music and not the size of my screen.
Summary: Product was very simple to connect. I had thought it would give me two independent screens (separate monitors from the notebook) which it does not, but displays the desktop across both monitors. But you can run different applications on different screens simply by moving them there so the effect is the same.
